Challenge
Getting error message: "Error: Not enough licenses. Please contact Veeam Customer Support at support@veeam.com."
Cause
This is typically caused by a host being rebuilt and given a new IP address or net name.
Solution
1. Go to Help -> License
2. Click Licensed Hosts
3. Select each of your hosts and press "Revoke"
More Information
License information is pulled on a job by job, VM by VM basis. Each time a job is run, each VM is verified against the host it is on to make sure that host is licensed. If the host is not licensed in Veeam yet, we will add it to the list of licensed hosts.
